Abstract: An electronic labelling assembly for a multi-part container includes a sleeve-shaped supplementary element which includes a coupling structure and which is configured to be coupled with respect to a longitudinal axis of the supplementary element by the coupling structure to an outer surface of a primary closure of the container and to surround the primary closure. The labelling assembly further includes an RFID functional unit having an RFID chip and an antenna structure coupled thereto. The supplementary element and the RFID functional unit are formed in coordination with each other and coupled to each other so that the RFID functional unit is attachable to the primary closure of the container by the supplementary element.

Abstract: A multifunctional label for a multi-part container has a transponder inlay with an electronic unit and a detection loop, which are arranged on a carrier layer of the transponder inlay and are coupled to one another in terms of signalling. The carrier layer has a predetermined local material weakening in the area of the detection loop. The multifunctional label further includes a label with at least one label layer which has a predetermined introduced local material weakening. The transponder inlay and the label layer are directly or indirectly coupled to one another, so that the material weakening of the label layer and the material weakening of the carrier layer overlap at least in sections with respect to a lateral extent of the multifunctional label.
